Valentin-Stefan Cobelea

I am using Fedora since its beginning, at home and of course at the office. Before Fedora, I was using RedHat Linux and I was deeply enjoying it.

I am a senior engineer in a Romanian office of a major U.S. Devices Software Optimization company, where I am a Development Engineer.

Activities within Fedora

File:Ambassadors Header AmbassadorsN1.png

I've been accepted as an ambassador.
Since in the area where I live there is no big activity regarding Linux, I'll do my best at work, to help my colleagues with Fedora related problems.
I've been accepted as a bug-zapper.
Established contact with the Romanian team from Fedora Project.
Bugs reporting (as many as I can do with ABRT).

Fedora and me

I like and use Fedora for everything I need. I want people to know about Fedora and what it could offer them.
When somebody needs help with some issue I always explain and show how to solve that.
I've created several documents that shows solutions for general problems, patches, manuals etc. All these things are really helping people, for instance here in the office where I work, because I see that there is no "publicity" for Fedora.
Looking at other Linux distros, I think branded CDs, DVDs and even USB-data sticks could make more people use Fedora.
